lynxpoint: Enable extra 16 IOAPIC entries for GPIO PIRQ
LynxPoint-LP has an additional 16 entries in the IOAPIC that can be assigned to specific GPIOs when they are configured as PIRQ. The maximum redirection entries field in the IOAPIC needs to be set to 0x27 when this is enabled. Additionally specific GPIOs need to be routed to PIRQ so they interrupt via the IOAPIC instead of the GPIO IRQ 14/15.
